About Tusar R.

Tusar R. holds a Master’s Degree in Physics from the National Institute of Technology (NIT) Silchar — a centrally funded Institute of National Importance under India’s Ministry of Education, consistently recognised for the rigour of its science and engineering programmes. He completed his undergraduate degree in Physics with a First Class A+ grade at Bir Bikram Memorial College (2018–2021), demonstrating academic excellence from the outset of his Physics career. His NIT Silchar MSc programme provided him with deep, research-informed training across the full spectrum of theoretical and applied Physics — the foundation on which his specialist tutoring capability is built.

Tusar teaches Mathematical Physics, Engineering Physics, Quantum Mechanics, Atomic Physics, Modern Physics, Nuclear Physics, Classical Mechanics, Thermal Physics, Wave Optics, Electronics, and Solid State Physics — one of the broadest subject coverages available on the My Physics Buddy platform. His teaching methodology is shaped by over three years of continuous, quality-assessed work as a Subject Matter Expert for both Chegg India and Straive — roles in which accuracy, clarity, and adherence to academic standards are verified externally. Sessions are structured around a diagnostic of the student’s existing understanding, followed by targeted concept development, mathematical methodology, and guided problem practice. Tusar’s strong analytical skills and research background mean he is equally comfortable explaining a concept from scratch and working through the advanced problem-solving techniques required at university level.


“Tusar has an impressive breadth of Physics knowledge — I have never asked him a question he could not answer clearly and precisely. He explains Solid State and Quantum Mechanics in a way that actually makes the material feel connected and logical, rather than like a pile of disconnected facts to memorise.”

How Sessions With Tusar Work

  1. Diagnostic Assessment: Tusar begins by identifying exactly where the student’s understanding currently stands — which concepts are solid, which are partially grasped, and where the gaps are that are creating difficulty in more advanced material. This targeted starting point ensures no session time is wasted on ground the student has already covered.
  2. Concept Explanation from First Principles: Tusar builds understanding from the foundational principles before introducing mathematical formalism or problem-solving procedure. This approach — consistent with NIT-level Physics pedagogy — ensures students understand why a result holds, not just how to reproduce it under exam conditions.
  3. Mathematical Methodology Development: For subjects such as Mathematical Physics, Quantum Mechanics, and Classical Mechanics, Tusar explicitly develops the mathematical tools the student needs — working through techniques in parallel with the physical content so that neither the mathematics nor the physics remains a black box.
  4. Guided Problem Practice: Students work through problems during the session with Tusar present — errors are identified and corrected in real time, problem-solving strategies are built up explicitly, and the student develops the independence and accuracy that university examinations demand.
  5. Targeted Feedback: After each problem or concept block, Tusar provides precise feedback — addressing not just what went wrong but why, and connecting each correction back to the underlying concept so the student understands the fix rather than merely accepting it.
  6. Cross-Topic Reinforcement: Tusar draws explicit connections between Physics disciplines — linking Solid State Physics to Quantum Mechanics, Thermal Physics to Statistical Mechanics, Atomic Physics to Modern Physics — helping students build an integrated understanding of Physics rather than siloed module knowledge.
  7. Progress Planning: Each session closes with a clear outline of what comes next, aligned to the student’s syllabus and examination timeline. Post-session summary notes are available on request at no extra cost, and all coordination is managed by the My Physics Buddy team via WhatsApp.
Whether you are facing a Quantum Mechanics exam, struggling with Mathematical Physics methods, or need to cover the full undergraduate Physics curriculum before a GATE or JAM examination — Tusar’s NIT Silchar training and verified subject matter expertise give you access to a tutor whose Physics knowledge is both deep and broad.

Frequently Asked Questions

How strong is Tusar’s academic background in Physics?

Tusar holds an MSc in Physics from the National Institute of Technology (NIT) Silchar — an Institute of National Importance under India’s Ministry of Education, recognised by the National Institutional Ranking Framework (NIRF) among India’s leading technical institutions. He completed his undergraduate Physics degree with a First Class A+ grade. His academic training covered the full theoretical and applied Physics curriculum at postgraduate level, giving him subject depth that spans all the disciplines he teaches.

What levels does Tusar teach?

Tusar teaches from advanced high school level through to undergraduate and postgraduate Physics. His core teaching depth is in the undergraduate Physics curriculum — covering all major disciplines from Classical Mechanics and Mathematical Physics through to Quantum Mechanics, Solid State Physics, Nuclear Physics, and Statistical Mechanics. He is also well-suited to students preparing for GATE Physics, JAM Physics, and CSIR-NET, whose syllabi map directly to his NIT MSc training.

Does Tusar help with assignments, problem sets, and exam preparation?

Yes. Tusar supports students with Physics assignments, problem sets, and examination preparation in full compliance with My Physics Buddy’s academic integrity policy — all submitted work is the student’s own. His role as a Subject Matter Expert on both Chegg India and Straive required him to produce detailed, accurate, step-by-step solutions to Physics problems — a skill he brings directly to student-facing tutoring. Post-session summary notes are provided on request at no extra cost.

What happens in the first session with Tusar?

The first session begins with a diagnostic: Tusar identifies which Physics topics the student is confident with, where the gaps are, and what the most efficient path through the syllabus looks like given the student’s exam date or coursework schedule. A structured session plan is built and shared at the end of the first session, giving the student a clear roadmap and removing the uncertainty of not knowing what to prioritise.

How is Tusar different from a general Physics tutor?

Tusar’s combination of an NIT Silchar MSc, a First Class A+ undergraduate degree, and over three years of externally quality-assessed subject matter expertise — across both Chegg India and Straive — places him in a category of verified Physics specialists that most tutors cannot match. His subject coverage is also unusually broad: he teaches confidently across twelve Physics disciplines at undergraduate level. For students studying multiple Physics subjects simultaneously, this means consistent, expert support from a single tutor rather than a patchwork of subject-specific coaches. Research from the University Grants Commission of India identifies subject breadth combined with postgraduate qualification as a strong indicator of effective Physics instruction at university level.

Can Tusar help with GATE Physics, JAM Physics, or CSIR-NET preparation?

Yes. Tusar’s NIT Silchar MSc curriculum maps directly to the syllabi of GATE Physics, IIT JAM Physics, and CSIR-NET Physical Sciences — all of which test the same theoretical and applied Physics disciplines in which he specialises. Sessions for these examinations are structured around systematic syllabus coverage, topic-by-topic problem practice, and the kind of analytical rigour these examinations demand. According to the GATE 2025 official portal, Physics is one of the most mathematically intensive papers in the examination — making the depth of the tutor’s subject knowledge a direct determinant of preparation quality.

Which international Physics curricula does Tusar cover?

Alongside Indian competitive exam preparation, Tusar covers Physics across international high school and undergraduate curricula. He is well-suited to students taking A/AS Level Physics, IB Physics HL/SL, and university-level Physics courses in the US, UK, Canada, and Australia — all of which overlap substantially with the Physics disciplines he teaches at undergraduate depth.


“Graduates of NIT Physics programmes bring a level of subject rigour and problem-solving discipline that is consistently reflected in their academic output. When this training is combined with verified, quality-assessed subject matter expertise across multiple professional platforms, the result is a tutor who can meet a student at any level of difficulty — and take them further than they expected to go.”
